Musical Chairs is a fun Redstone Mini Game created by DucksTheName.
You have someone go inside the Console, pick the difficulty (easy/hard), and all the players get into position on the random colored wool in the lava. The director will then pick one of the colors, and everyone that is playing will see the color that was picked light up on the screen. They then will try to run and jump as fast as they can to the appropriate color that was chosen. They only have 5-6 seconds to do so on Normal difficulty, and 1-2 seconds on Hardcore.
It's very simple to play, so be sure to paste it somewhere everyone can enjoy!
